摘　　要： 基于可拓学工程方法,在物元模型理论的基础上建立工程岩体质量评价的物元模型,应用可拓集合的关联函数,建立基于物元和关联函数的工程岩体可拓评价方法,对新疆东戈壁露天矿主要工程岩体质量进行评价,并与传统的"RMR、Q"法评价结果作比较。研究结果表明:得出的评价结果与现场实际相符合。工程岩体质量的可拓学评价不仅可以反映岩体属于何种质量等级,而且可以反映工程岩体与其他质量等级的"距离",能较好的反应工程岩体的质量等级,具有较好的适用性。 The matter element model of rock quality evaluation was established using matter element model theory based on theory of extenics.The extenics evaluation model for rock mass was proposed based on matter element theory and the dependent function of extenics set.The main engineering rock mass quality was evaluated by this method in Dong Gebi open-pit mine,and the result was compared with that by the traditional ＂RMR,Q＂ method.The result is in accordance with the actual situation.The engineering rock mass quality based on theory of extenics evaluation can not only reflect qualitatively the rock mass quality grade,but also define quantitatively the rock mass quality grade through a factor called ＂distance＂,so it indicates the rating of engineering rock mass,and has good applicability.
